Spatial trends of Potamogetonaceae along an altitudinal gradient
Biologia, 2020 Studying the effect of altitude on species distribution may help us to predict the response of species to future climate changes, which will likely cause upward migration of vegetation zones. In this study, we aimed to analyze distribution and abundance patterns of Potamogetonaceae along an altitudinal gradient and to determine the species ...

Altitudinal Gradient of Evapotranspiration in Tropical Highlands
, 2022 Tropical highlands supply water for large cities in the Andes. Based on meteorological records from three weather stations in the paramo Chingaza, Colombia evapotranspiration (ET) is estimated based on the Penman-Monteith (P-M) approach to compare the altitudinal variation and assess the radiation and aerodynamic effects on the water losses.

Behavioural tuning in a tropical amphibian along an altitudinal gradient [PDF]
Biology Letters, 2017 Males of the coqui treefrog,Eleutherodactylus coqui, produce a distinct two-note ‘co-qui' advertisement call from sunset to midnight throughout most of the year. Previous work established that both the spectrotemporal aspects of the call and the frequency of highest inner-ear sensitivity change with altitude above sea level.

El efecto del fuego y las características topográficas sobre la vegetación y las propiedades del suelo en la zona de transición entre bosques y pastizales de las sierras de Córdoba, Argentina [PDF]
, 2013 En el contexto actual de cambio climático, el estudio de la dinámica de las zonas de transición entre bosques y pastizales tiene un papel fundamental, tanto a nivel científico como en la planificación del manejo de los ecosistemas.

Wood density variation across an Andes‐to‐Amazon elevational gradient
Journal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

Macrofungi of the altitudinal gradient, Northern Rocky Mountains [PDF]
, 2021 Macrofungal communities of four altitudinal zones of the Northern Rocky Mountain region are described and compared with respect to species richness, production (g/100m2/yr), functional structure (mycorrhizal vs. decomposer), seasonality of activity and relationship to temperature and rainfall.

Análisis de la concentración de carbono y composición vegetal en humedales de páramo altoandinos en una gradiente altitudinal en el Parque Nacional Cayambe Coca [PDF]
, 2017 Andean paramos are tropical ecosystems whose topographic and climatological patterns allow the formation of peatlands, which are flooded or semi-flooded areas that accumulate large layers of organic soil called peat.
